使用：

package com.saxon.shiro.config;

import springfox.documentation.builders.RequestHandlerSelectors;

import java.util.ArrayList;

@Configuration
@EnableSwagger2
public class Myswagger {
    @Bean
    public Docket docket () {
        return new Docket (DocumentationType.SWAGGER_2)
                .select ().apis (RequestHandlerSelectors.basePackage ("com.saxon.shiro.controller"))//选择扫描的包
                .build ().
                        groupName ("saxon")//设置这个组的名字
                .apiInfo (
                        new ApiInfo (

                                "urn:tos",//连接
                                new Contact (//作者信息
                                        "莫松",
                                        "2433027822@qq.com",
                                        "2433027822@qq.com"),

                                new ArrayList ()));
    }
}

多个组多个类

异步请求

使用注解的话，就是两个注解

@Async：声明这是一个异步方法
@EnableAsync：开启异步功能

使用这个注解的时候，方法的对象就不能是接口的实现类，一定要是接口，不然会报错；

邮件发送

下面的配置和我们以前再Javaweb里面的配置一样，所以我们可以明白的发现一些属性我们都可以，简单来说就是autoconfiguration里面的属性

mail:
  username: "2433027822@qq.com"
  password: "sxvwxjiohejodigg"
  properties:
    mail:
      smtp:
        ssl:
          enble: true
  host: "smtp.qq.com"

只需要一个start就可以运行；

简单的邮件：

@Autowired
    JavaMailSenderImpl mailSender;

    @Test
    void contextLoads () {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage ();
        simpleMailMessage.setText ("你好");
        simpleMailMessage.setSubject ("你好");
        simpleMailMessage.setTo ("2433027822@qq.com");
        simpleMailMessage.setFrom ("2433027822@qq.com");
        mailSender.send (simpleMailMessage);

    }

复杂的邮件：

@Autowired
   JavaMailSenderImpl mailSender;

   @Test
   void contextLoads () throws MessagingException {
       MimeMessage mimeMessage = mailSender.createMimeMessage ();
       //组装
       MimeMessageHelper mimeMessageHelper = new MimeMessageHelper (mimeMessage,true);//是不是多部份的邮件
       mimeMessageHelper.setText ("<p style='clolr=red'>我是你爹</p>", true);//是否识别HTML代码
       mimeMessageHelper.addAttachment ("1.jpg", new File ("D:\\壁纸\\b.jpg"));//attachment：附件
       mimeMessageHelper.setFrom ("2433027822@qq.com");
       mimeMessageHelper.setTo ("2433027822@qq.com");
       mimeMessageHelper.setSubject ("复杂邮件");
       mailSender.send (mimeMessage);
   }
